Title: Improvements in or relating to a process for rapid curing of polyurethane castings
IPC: C08G18/10
Filed: 1953-07-17
Abstract: A polyurethane casting fluid containing terminal isocyanate groups is cured by heating it in a mould in the absence of moisture until the fluid becomes solid enough to hold its shape and resist blowing on subsequent exposure to moisture, and then exposing the semi-cured stock to hot water or steam to complete the cure.  The polyurethane is made by reacting a linear polyester containing terminal hydroxy groups or a polyalkylene glycol with an excess of a diisocyanate. Many polyester-forming reactants and diisocyanates are specified and preferably the molar ratio of diisocyanate : polyester is 1.01 to 2 : 1.  The casting fluid may also contain a polyfunctional hydroxyl curing agent, e.g. a glycol, a small amount of a triol, a low molecular weight linear polyester contain ing terminal hydroxyl groups or a polyester containing bound glycerol.  Bubbles in the cured product may be eliminated by degassing under vacuum prior to casting or by adding a plasticiser, e.g. diphenyl octyl phosphate, tricresyl phosphate, methyl phthalate, benzyl phthalate, benzyl sebacate, tetrahydrofurfuryl adipate, acetyl tributyl citrate, butyl diglycol carbonate, tributyl phosphate, N.N-dibutyl benzene sulphonamide, phenyl naphthyl ketone, phenyl ether, o-nitrobiphenyl and isoheptyl diphenylamine.  In Examples (2) and (4), 1 mol. of hydroxyl polyethylene adipate (M.W. 1120) is stirred at 90-95 DEG  C. with 1.5 mols. of p-phenylene diisocyanate; 1.4 mols. of ethylene glycol are added, the mixture evacuated and poured into a sheet mould.  The sheet is cured for 1 or 16 hours at 150 DEG  C. and then immersed in boiling water or suspended in steam at 100 DEG  C. for 1 hour.  (5) 1 mol. of hydroxyl polyethylene adipate (M.W. 1050) is heated with 1.07 mols. of p-phenylene diisocyanate at 90-100 DEG C. and the resulting fluid poured into a mould.  The product is cured for 16 hours at 150 DEG C. and then suspended in steam at 100 DEG C. for 1 hour.  (6) The polyesterurethane from 1 mol. of hydroxyl polyethylene adipate (M.W. 1300) and 1.07 mols. of p-phenylene diisocyanate is poured into a pellet mould, heated for 20 hours at 120 DEG  C. and the resulting rubbery pellets submerged for 1 hour in boiling water. (8) and (10) The polyesterurethane from 0.1165 mols. of hydroxyl polyethylene adipate (M.W. 1370) and 0.175 mols. of m-phenylene diisocyanate is mixed with 0.0524 mols. of hydroxyl polyethylene adipate containing bound glycerol and the mixture poured into a mould and cured at 150 DEG  C. for 90 minutes.

Title: Improvements in or relating to fluid counters
IPC: F15C1/12
Filed: 1965-05-11
Abstract: 1,102,002. Reversible binary counter. R. W. WARREN. 11 May, 1965 [11 May, 1964], No. 19890/65. Heading G4P. A reversible binary counter has a plurality of pulse converters 121, 122 (Fig. 1b, and Fig. 2, not shown), 123, 124 (Fig. la) the state of each of which represents one of the digits of a binary number. In one embodiment (Figs. la and 1b) if, for example, the number stored in the counter is 5, i.e. converter 124 is in its " 0 " state (flow along channel 179), converter 123 is in its " 1 " state (flow along channel 178) converter 122 is in its " 0" state (flow along channel 175) and converter 121 is in its " 1 " state (flow along channel 174) and a count forward pulse is received at channel 172 the first converter 121 is switched to its " 0 " state. Since, on commencement of the pulse along channel 172, flow existed along channel 174, AND gate 132 is enabled, the resultant output flow along channel 190 switching the converter 122 to its " 1 " state. Since, initially, there was no flow along channel 176, AND gate 134 is not enabled and since there is consequently no flow along channel 192, AND gates 136, 138 remain closed and so converters 123, 124 do not change state. The final state of the counter is thus 0110 representing the digit 6. If the counter is in its 1000 state and a count backward pulse is received on the input channel 171, the converter 121 is switched to its " 1 " state. Since initially there was flow along channel 173, AND gate 131 is enabled so that the converter 122 changes state. Since there was also flow in channels 173, 175, AND gate 133 is open so that, on commencement of the count backward pulse, AND gate 135 is enabled to change the state of converter 123. Similarly gates 137, 139 are enabled to change the state of converter 124 so that finally the counter is in its 0111 state. In another embodiment (Fig. 2, not shown) input pulses are received only on one channel (201), flow in the input channels (213, 214) of a flipflop (211) indicating that the count is to be forwards or backwards respectively.
